I saw a few references to some fixes to something relating to "iounmap" in the
new 2.6.11 kernel that he saw in the logs on every X freeze. So, I grabbed the
latest vanilla kernel from www.kernel.org (2.6.11.7) and compiled it for him and
made it into a .deb and told him to install it and boot it and see if the X
freezes persist. After upgrading to that kernel version, without changing
anything else, X hasn't frozen, yet, after over 10 hours of it being up. No
changes were made to X.org's configuration when switching from the default
kernel 2.6.10 included in Kubuntu to 2.6.11.7 from www.kernel.org. So, that is
making me believe that somehow this X freezing is relating to something in the
kernel itself.
